Physics HELP

You have a converging (convex) lens and a diverging (concave) lens and the magnitude of the focal length of each lens is 38.5 cm.

(a) Determine which lens you should use in order to produce an image of a light bulb on a screen several metres away.

(b) Determine how far from the lens you should locate the screen in order to produce an image of the light bulb that is magnified by a factor of 2.10.

    Because a concave lens cannot form a real image of a real object, it is difficult to measure its focal length precisely. One method uses a second, convex, lens to produce a virtual object for the concave lens. Under the proper
